PB Blaster'd the sheared-off bolt that was stuck in the crankcase for a few days and managed to get it out yesterday -
Shit design by the 70's Hondajin has to be said. The thread in the crankcase where this bolt bolts into is open on the rear to the elements so guess what, the elements get in and do their worst. Bolt was totally rusted in there -
I'm going to be using stainless bolts when I button the transmission cover back on, but may plug up that hole anyway with some JB Weld for good measure. Can't imagine who thought it was a good idea to keep that open in the first place.
The sheared timing cover bolt was a different story. Tried getting the thing out with an extractor but no joy. Looked like it had been cross-threaded - wasn't budging for love or money. Balls to it, it can stay there - I'll attach the covers using the outer bolts only.
Got the timing belts replaced, no drama -
Question though. Octane's well documented info on how to change the belts was a godsend, but I was a little unclear on how to set the tension on the right-side (when sitting on the bike) belt. Once I'd installed both belts and tensioners (loosely), I then set the tension on the left belt, then rotated the crank through 360° so the timing marks were pointed inwards, then set the tension on the right belt. Is that all there is to it?
